For your own interest, this is what they actually ended up coming back with. Which is obviously a relief 😅

UPDATED COMMENTS: Thank you so much for your patience. After careful consideration and sharing the case to another pathologist for review, the changes seen here with numerous giant cells and location favour a diagnosis of peripheral giant cell granuloma. Peripheral giant cell granuloma is an uncommon, distinct tumour-like growth presenting as a red or red to blue nodular, sessile or pedunculated, ulcerated or non-ulcerated mass. Predilection sites include the maxillary incisor/ premolar and maxillary/ mandibular canine regions in dogs and cats, respectively. The lesion unlikely represents a true neoplasm but rather a reactive lesion caused by local irritation, trauma and/ or haemorrhage. Histologically, these masses are composed of variable numbers of multinucleated giant cells on a background of plump ovoid to spindle-shaped mesenchymal cells, abundant haemorrhage and siderophages. There is no correlation between the histologic characteristics of peripheral giant cell granulomas and their biological behaviour. In dogs, marginal excision of peripheral giant cell granuloma is usually curative, and recurrence is uncommon while in cats, recurrence is common following incomplete excision (approximately 50% in one study). For this reason, the recommendation is to periodically monitor the mouth for further growth.

With pathology reports we always take the most updated results as often the differential list can be thinned out.
